Specification of Letters Patent.

Patented Mar. *7, 1911.

To all whom 'it 'may concern:

lle it known that we, Omvnu l). KRAFT and Louis W. F n'rzuu, citizens of the United States, residing at Findlay, in the county of lrlancock and State of Ohio, have invented new and useful Improvements in Well Pulling and Cleaning Machines, of which the following is a specification.

Our invention relates to improvements in machines in the use of which sucker rods. tubings, or casings can be applied to and removed from oil wells, and in the use of which a well may be bailed or cleaned, the invention being particularly directed to improvements in a well pulling machine for which we were issued Letters-Patent of the United States, numbered 836,989, and dated May 5, 19.08.

The invention consists in the construction, combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawings, wherein Figure 1 isa view in side elevation of a well pulling and cleaning machine constructed in accordance with out invention. Fig. 2 is a top plan view of the machine, the derrick, the derrick supporting standards, and the derrick guiding bars being omitted. Fig. 3 is a sectional view taken on the plane indicated by the line 3-3 of Fig. 2, looking in the direction indicated by t-he arrow. Fig. +1 is a detail perspective view of one of the levers and a member by which it is secured in applied posit-ion. Fig. is a. detail perspective view of one of the friction gears.

Like reference characters are used to designate corresponding parts throughout the several views.

Of our improved well pulling and cleaning machine, 2 designates the traction wheels and 3 the steering wheels thereof. Upon the axles t ,5 of the wheels is mounted the main frame of the machine, said frame comprising longitudinal beams or girders 6-7 and transverse beams or girders 8, 9, 10, 11, a-nd 12. The main frame also comprises a longitudinall beam or gir-der 13, all of the beams or girders being suitably united and braced. The steering wheels 3 can be controlled through the me dium of a steering mechanism which includes a shaft 14C which is journaled in depending' bracket. arms l5, and which is pro* vided with a worm-wheel 16. The steering mechanism also includes a steering post 17 which is journaled in a bearing 18 and which provided at its upper end with a hand wheel 19. The bearing 18 is secured to the transverse beam or girder 10. A worm 20, which meshes with the worm-wheel 16, is secured to the lower end of the steering post 17. A chain 21 is suitably wound about the shaft 14, and it is secured at its ends to rods 22 which are suitably connected to the axle of the steering wheels 3. The rods 22 include turn buckles 23, by means of which any slack occurring in the chain may be taken up.

A11 engine -2A of the explosive type, is secured to the longitudinal beams or girders 7 and 13, and t-he piston rod 25 thereof is connected to the crank 26 of the shaft 27 which is journaled in bearings 28, the bearings being secured to the longitudinal beams or girders 6 and 7. Fly wheels 29 are secured to the shaft 27, one on each side of the crank 26. A. belt pulley 30 is also secured to the shaft 27, said shaft to be referred to hereinafter as drive shaft.

At the forward end of the machine, a

vdriven shaft 31 is journaled in bearings 32 which are secured to the longitudinal beams or girders 6 and 7. A drum 33, which is provided with a plurality of winding surfaces of various diameters, is fixed upon the shaft 3l. A drive-wheel 34 of the friction type is fixed upon the shaft 31 at one end of the drum 33, and is provided with a brake wheel 35 about which passes a brake band 36. The ends of the brake band 36 are secured to a stub shaft 37 journalcd on the longitudinal beam or 4gjirder 7. A lever 33, which is provided with a handle 39, is secured to the stub shaft 37. When said lever is depressed the brake. band 36 is tightened about the brake wheel 35, and when elevated the brake band is loosened from about the wheel.

A pair of bracket arms 40 are respectively pivoted to the longitudinal beams or girders 0 7, and are provided :it their free ends with bearings 4l in which a transmission shaft. 42 is journaled. A pulley 48 and a friction gear 44 are fixed upon the transmission shaft. 42, this shaft being under the col'itrol of a lever so that the friction. gear .may be thrown into and out of engagement'. vwith the drive wheel 34. The lever 45 is provided with a, handle 40 and is secured to a shaft 47 which is connected with the traiisn'iission shaft 42 by ineans of rods 48. lThe rods 48 are each secured at one end to the bearings 41. The opposite ends of the corniecting rods 48 are secured lto eccentric straps 49 which pass about eccentrics 50 which are secured to the shaft 47. then the friction' wl'ieel 44 is thrown into engagen'lcnt with the drive wheel 34, the drum 38 is rotated in winding direction at low speed.

Depending bracket arms 51 are respectively pivoted to the longitudinal beams or girders 0 and 7, directly beneath the bracket arms 40. Bearings 52 are secured to the free ends of the. bracket arms 51. and journaled in said bearings is a shaft upon which a pulley 54 and a friction gear 55 are fixed. The shaft 553 is under the control of a lever 50 so that the friction gear 55v is thrown into and out of enga-gement with the drive wheel 34. The lever 56 is provided with a handle 57 and is secured to a shaft 80 which is journaled on the longitudinal beams or girders 0 7. Connecting rods 59 are secured at one end to the bearings 52, and at their opposite ends to eccentric straps 60, the straps passing about eccentrics 61 which are fixed upon the shaft 58. lVhen the friction gear 55 is in engagement with the drive wheel 84, the drum 38 is rotated in winding direct-ion at high speed.

A belt- 62 passes about the pulleys 80, 43, and 54, and about a tension pulley 63. The tension pulley 68 is journaled between the upper ends of a pair of bracket arms 64 which are pivoted at their lower ends to a member G5 which is suitably supported o-n the longitudinal beams or girders G and 18. A U-shaped bracket 66 is secured to the upper ends of the bracket arms (34 and has connected therewith a. bolt 07 which passes through a guide 68 secured to the transverse beam or girder 11. A coiled eXpansion spring 69 is mounted upon the bolt 67 between the guide 68 and a nut 70 mounted upon the bolt. The tension pulley 63 keeps the belt 62 taut. As the pulley 54 is smaller than the pulley 48, the friction gear 55 is driven faster than the friction gear 44, permiting the drum to be rot-ated in winding direction at one of two speeds.

A shaft 71 is journaled on the longitudinal beams Gd'?, and is rovided with a forwardly projecting arm 2, at the free end of which is journaled a friction rear 78. A lever 74 is secured to the shaft 71, and provides means by which said shaft may be moved to throw the friction gear 7 3 into and out of engagement with the drive wheel 34 and the friction gear 44. When the friction gear 7 3 is in engagement with the drive wheel 34 and the friction gear 44, the drum 8? is rotated in unwinding direction at low peed. :lt shaft 75 is journaled on the transverse beam or girder t) and is provided with a pair of forwardly projecting arms 76 to the outer ends of which is pivot-ally secured a pair of depending arms 77. A friction gear 78 is iournaled between the arms 7 7 and adapted to be moved into and out of engagement with the drive whcel84 and friction gear lVhen the friction gear 78 is in engagement with the drive wheel 84 and the friction gear 55 the drum is rotated in unwinding direction at high speed. The shaft 75 is under the control of the lever 70 which is pivotally secured at 58 to the longitudinal beam or girder 0. The lever 79 is connected to a crank arm 81 secured to the shaft 75 by means of a rod 82. All exceptthe levers 79 are connected to their respective shafts through the medium of flanged collars 83 which are secured to the shafts in any suitable manner. The flanges 84 of the collars 83 are each provided with an annular series of openings 85. Each lever is provided with a curved end 8G, and with openings 87, bolts passing through the openings 87 and through a pair of the openings 85 to secure the lever in applied position. 1n view of the manner in which the levers are secured in applied position, they may be adjusted upon the shaft to compensate for any wear in the friction gears 44. 5o. 48 and 78. and in the drive wheel 34, whereby the levers may, at. all times, occupy certain normal positions.

The derriek used in connection with the machine may be of any appropriate type. The one shown in Fig. 1 of the accompanying drawings consists of the mast. 89 to the upper end of which is secured a pulleyT 99. At its lower end the mast 89 is pivotally and slidably mounted on standards 102 by means of a shaft 108. The standards are mounted upon the front end of the machine frame. In view of its connection with the standards 102. the mast may be folded down upon the machine and when so folded it is supported by cross bars` not shown, one cross bar being carried by standards rising vertically from the rear end of the machine. The frame 100 is pivotally secured to the standard 102 and is provided with a pulley 107. The frame may also be folded down upon the machine and is adapted to be supported in an upright position by rods 108. The rods 108 are each secured at one end to the frame 100 and are adapted to be detachably secured at their rear ends to the standards 100 by pins .109, openings 110 vand levers 111. The guy rope of the derrickis adapted to pass overthe pulley .-107 when the machine is in use.

The standards 100 and 102, and thederrick are not shown in Fig. 2 of the drawing.

Then it is desired to pull or clean a wel the derrick is erected and the engine started, after which a cable, not shown, is partially wound upon the drum 33. The cable passes over the pulley 99 ofthe derrick, anda suitable cleaning or pulling device is secured to the free end thereof. Then itis desired to wind the cable upon` the drum at low speed the friction gear 44 is thrown into engage ment with the drive Wheel 34 through thc medium ofthe lever 45, and when it is desired to wind the cable upon the drum at` high speed the friction gear 44 is thrown out of engagement with the drive wheel 34 and the friction gear 55thrown into engagement with such wheel, the friction gear 55 being operable throughr the medium of levers 56. Vhen it is desiredvto unwind the' cable from the drum at 'low speed, the friction gear 73 is thrown into engagement with the friction gear 44 and the drive wheel 34, while when it is desired to unwind the cable from the drum at high speed the friction gear 73 is thrown out of engagement with the friction gear 44 and the drive wheel 34 and the friction gear 78 isfthrown into engagement with the friction gear 55 and the said wheel. The gear 73 is operable through the medium of the lever 74, and the gear through the medium of the lever .79. To secure the drum 33 against rotation the brake band 36 is tightened on the brake wheel 35 through the medium of the lever 38.

A shaft 113 -is journaled in bearings 114V secured to the longitudinal beams or girders 7 and 13. .A sprocket wheel 115 1s secured to one end of the shaft 113, and a crank 11G is secured to the opposite end of said shaft, a grooved pulley 117 being journaled on thc outer end of the crank. A sprocket wheel 11S is loosely mounted upon the shaft 42, and a sprocket chain 119 passes about said wheel and the wheel 115. A clutch element 120 is splined upon the shaft 42 `and is provided with lugs 121 which are adapted to enter recesses 122 in the hub of the sprocket wheel 118. Then the lugs 121 are in engagement with the recesses 122. the sprocket wheel 118 is fixed on the shaft 42 for rotation therewith.; rotating the grooved pulley 117. The clutch element 120 is carried by a lever y123 by means of which it may be thrown into and out of engagement with the sprocket wheel 113. The lever 123 is secured in applied position by means of a pin 124 which passes through the lever and through an arm 125 carried by the longitudinal beam or girder 7 Then cleaning a A126 journaledvon a -standard 127 which is secured to and vrises from the transverse beam or girder 10, and underthegrooved pulley 117, the rotation of the pulley 117 alternately raising .the cleaning tool from and dropping it on the'bottom of the well.

A differential gearing 128 is mounted upon the rear axle 4, and a sprocket wheel 129 is mounted upon the-shaft 31 of the drum A sprocket chain 13() passes about the differ` ential gearing 12S and the sprocket wheel 129, whereby to permit the machine Ato be propelled from the drum shaft 31. The sprocket wheel 129 is loosely mounted upon the drum shaft 31 and is adapted to be fixed thereon for rotation therewith by means of aclutch element 120 which is provided with lugs 131v adapted to enter recesses 132 in the sprocket wheel. The clutch element is adaptedto be thrown into andout of interlocking connection with the sprocket wheel 129 by means of a lever 133 which is pivotally mounted upon an arm 134 secured to-the longitudinal beam or girder 6. -The lever is adapted to be secured inadjusted position by means of a pin 135 which passes through the lever and through an larm 136 secured to the longitudinal beam or girder G.

rA seat, not shown, is secured to the main frame of the machine in .rear of the hand wheel 19, andit is adapted to be occupied when the machine is under way. To permit the occupant of the seat to control the speed of the machine, levers 137 and 13S are pivotally `mounted at a point adjacent the seat, said levers being respectively connected tothe shafts 50 and 80 by rods 139. The rods 139 are adjustably connected to the shafts through the medium of flanged collars 140 and bolts 141. The construction of the flanged collars and the manner in which the levers are secured thereto is fully disclosed in Fig. 4 of the drawings.

The drive chain 130 is tensioned by a sprocket wheel 142 which is journaled on a spring pressed lever 143. The lever 143 is pivotally mounted upon-an arm 14.4 depending from the longitudinal beam or girder G, and a spring 145 is secured at one end to the lever and at its opposite end to the bracket arm.15.

It should be apparent from the above description, taken in connect-ion with the accompanying drawings, that we provide a machine which is admirably adapted for thelpurpose for which it was intended,.which is comparatively simple of construction, and which may be manufactured and sold at a comparatively low cost.
